Cost and Reimbursement for Three Fibroid Treatments: Abdominal Hysterectomy, Abdominal Myomectomy, and Uterine Fibroid Embolization

Comparing magnetic resonance imaging and ultrasound in the clinical evaluation of fibroids prior to uterine artery embolization

PURPOSE

Uterine artery embolization has become established as a frontline treatment for uterine leiomyomata. In planning embolization, preprocedural imaging can further characterize pathology and anatomy, but it may also reveal coexisting diagnoses that have the potential to change clinical management. The purpose of this study is to compare the diagnostic outcomes of ultrasound and MRI performed for patients prior to undergoing embolization.

METHODS

The study cohort consisted of 199 patients who underwent uterine artery embolization at a single academic institution between 2013 and 2018. Prior to embolization, all patients had an MRI confirming a leiomyomata diagnosis. Additionally, 118 patients underwent transvaginal ultrasound within five years prior to MRI. MRI findings were analyzed and, when applicable, compared to prior ultrasound impressions to assess for the incidence of new findings. The diagnoses of interest were adenomyosis, hydrosalpinx, predominantly infarcted leiomyomata, and large intracavitary leiomyomata. Data were collected from retrospective chart review and included demographics, symptomology, and imaging reports.

RESULTS

199 patients ultimately underwent embolization for treatment of MRI-confirmed leiomyomata. Of 118 patients who also had an ultrasound within five years prior to their MRI, 26 (22.0%) received a second gynecologic diagnosis based on MRI findings that was not previously seen on ultrasound. Of 81 patients who only had an MRI before embolization, 19 (23.5%) received a second gynecologic diagnosis not previously documented. The most common coexisting pathology was adenomyosis, presenting in 34 (17.1%) patients with leiomyomata, followed by large intracavitary leiomyomata (8, 4.0%), infarcted leiomyomata (7, 3.5%), and hydrosalpinx (6, 3.0%),.

CONCLUSIONS

When considering uterine artery embolization for the treatment of symptomatic leiomyomata, preprocedural MRI is superior to ultrasound in detecting coexisting pathologies, including adenomyosis and hydrosalpinx. It can also better characterize leiomyomata, including identifying lesions as intracavitary or infarcted. These findings have the potential to alter clinical management or contraindicate embolization entirely.

True Costs of Uterine Artery Embolization: Time-Driven Activity-Based Costing in Interventional Radiology Over a 3-Year Period

PURPOSE

The aim of this study is to uncover potential areas for cost savings in uterine artery embolization (UAE) using time-driven activity-based costing, the most accurate costing methodology for direct health care system costs.

METHODS

One hundred twenty-three patients who underwent outpatient UAE for fibroids or adenomyosis between January 2020 and December 2022 were retrospectively reviewed. Utilization times were captured from electronic health record time stamps and staff interviews using validated techniques. Capacity cost rates were estimated using institutional data and manufacturer proxy prices. Costs were calculated using time-driven activity-based costing for personnel, equipment, and consumables. Differences in time utilization and costs between procedures by an interventional radiology attending physician only versus an interventional radiology attending physician and trainee were additionally performed.

RESULTS

The mean total cost of UAE was $4,267 ± $1,770, the greatest contributor being consumables (51%; $2,162 ± $811), followed by personnel (33%; $1,388 ± $340) and equipment (7%; $309 ± $96). Embolic agents accounted for the greatest proportion of consumable costs, accounting for 51% ($1,273 ± $789), followed by vascular devices (15%; $630 ± $143). The cost of embolic agents was highly variable, driven mainly by the number of vials (range 1-19) of tris-acryl gelatin particles used. Interventional radiology attending physician only cases had significantly lower personnel costs ($1,091 versus $1,425, P = .007) and equipment costs ($268 versus $317, P = .007) compared with interventional radiology attending physician and trainee cases, although there was no significant difference in mean overall costs ($3,640 versus $4,386; P = .061).

CONCLUSIONS

Consumables accounted for the majority of total cost of UAE, driven by the cost of embolic agents and vascular devices.

Patient Characteristics Associated With Embolization Versus Hysterectomy for Uterine Fibroids: A Systematic Review and Meta-Analysis

INTRODUCTION

Black and underinsured women in the United States are more likely than their counterparts to develop uterine fibroids (UFs) and experience more severe symptoms. Uterine artery embolization (UAE), a uterine-sparing therapeutic procedure, is less invasive than the common alternative, open hysterectomy. To determine whether demographic disparities persist in UF treatment utilization, we reviewed patient characteristics associated with UAE versus hysterectomy for UF among studies of US clinical practices.

METHODS

A systematic literature review was conducted via PubMed, Embase, and CINAHL (PROSPERO CRD42023455051), yielding 1,350 articles (January 1, 1995, to July 15, 2023) that outlined demographic characteristics of UAE compared with hysterectomy. Two readers screened for inclusion criteria, yielding 13 full-text US-based comparative studies specifying at least one common demographic characteristic. Random effects meta-analysis was performed on the data (STATA v18.0). Egger's regression test was used to quantify publication bias.

RESULTS

Nine (138,960 patients), four (183,643 patients), and seven (312,270 patients) studies were analyzed for race, insurance status, and age as predictors of treatment modality, respectively. Black race (odds ratio = 3.35, P < .01) and young age (P < .05) were associated with UAE, whereas private insurance (relative to Medicare and/or Medicaid) was not (odds ratio = 1.06, P = .52). Between-study heterogeneity (I2 > 50%) was detected in all three meta-analyses. Small-study bias was detected for age but not race or insurance.

CONCLUSIONS AND IMPLICATIONS

Knowledge of demographic characteristics of patients with UFs receiving UAE versus hysterectomy is sparse (n = 13 studies). Among these studies, which seem to be racially well distributed, Black and younger women are more likely to receive UAE than their counterparts.

Care Delivery for Patients with Leiomyomas: Failures, Real-Life Experiences, Analysis of Barriers, and Proposed Restorative Remedies

In this narrative review, we describe historical and contemporary influences that prevent patients with fibroids from getting appropriate medical care. Using patient stories as examples, we highlight how misogyny on all levels hurts patients and prevents medical teams from doing their best. Importantly, inequity and disparities result in massive gaps in care delivery. We suggest that we, as gynecologists and surgeons, must join public discourse on this topic to highlight the inadequacies of care delivery and the reasons behind it, suggest potential solutions, and join patients and communities in formulating and implementing remedies.

Invasive Procedural Treatments for Symptomatic Uterine Fibroids: A Cost Analysis

PURPOSE

The aim of this study was to evaluate the contemporary use of procedural interventions to treat symptomatic uterine fibroids and assess associated health care system costs.

METHODS

Using the IBM Watson MarketScan Commercial Claims and Encounters database for 2009 to 2015 and relevant International Classification of Diseases diagnosis codes, women aged 18 to 55 years with clinically significant uterine fibroids were identified. Using Current Procedural Terminology codes, relevant procedural interventions were identified (hysterectomy, endometrial ablation, myomectomy, and uterine fibroid embolization [UFE]). Costs were defined as total actual payments by insurers and patients (per procedure and per episode of care) and were adjusted and compared using generalized linear models.

RESULTS

Of 241,757 invasive procedures for fibroids, hysterectomy was most common (76.5%), followed by endometrial ablation (14.5%), myomectomy (4.7%), and UFE (4.3%). Hysterectomy was more common in older women and those in rural areas (65.2% of patients <40 years of age, 77.6% of those 40-49 years of age, and 83.6% of those 50-55 years of age; 83.9% of patients outside versus 75.3% within metropolitan statistical areas). Per procedure, adjusted mean costs were $3,188 (95% confidence interval [CI], $3,114-$3,264) for hysterectomy, $2,781 (95% CI, $2,695-$2,870) for ablation, $4,436 (95% CI, $4,256-$4,623) for myomectomy, and $6,161 (95% CI, $5,736-$6,617) for UFE. Adjusted mean costs for entire episodes of care were $14,676 (95% CI, $14,496-$14,858) for hysterectomy, $6,702 (95% CI, $6,534-$6,875) for endometrial ablation, $14,791 (95% CI, $14,465-$15,125) for myomectomy, and $13,873 (95% CI, $13,182-$14,599) for UFE.

CONCLUSIONS

Of invasive procedures for symptomatic uterine fibroids, hysterectomy was used more frequently than endometrial ablation, myomectomy, and UFE combined. Per procedure and per episode, ablation was least costly. Costs per episode were similar for hysterectomy, myomectomy, and UFE.

Women with Newly Diagnosed Uterine Fibroids: Treatment Patterns and Cost Comparison for Select Treatment Options

The primary objective of this study was to describe surgical treatment patterns among women with newly diagnosed uterine fibroids (UF). A secondary objective was to estimate the medical costs associated with other common surgical interventions for UF. Claims-based commercial and Medicare data (2011-2016) were used to identify women aged ≥30 years with continuous enrollment for at least 12 months before and after a new diagnosis of UF. Receipt of a surgical or radiologic procedure (hysterectomy, myomectomy, endometrial ablation, uterine artery embolization, and curettage) was the primary outcome. Health care resource utilization and costs were calculated for women with at least 12 months of continuous enrollment following a UF surgical procedure. Among women who met selection criteria, 31.7% of patients underwent a surgical procedure; 20.9% of these underwent hysterectomy. An increase was observed over time in the percentage of women undergoing outpatient hysterectomy (from 27.0% to 40.2%) and hysteroscopic myomectomy (from 8.0% to 11.5%). The cost analysis revealed that total health care costs for hysteroscopic myomectomy ($17,324) were significantly lower (P < 0.001) than those for women who underwent inpatient hysterectomy ($24,027) and those for women undergoing the 3 comparison procedures. Hysterectomy was the most common surgical intervention. Patients undergoing inpatient hysterectomy had the highest health care costs. Although less expensive, minimally invasive approaches are becoming more common; they are performed infrequently in patients with newly diagnosed UF. The results of this study may be useful in guiding decisions regarding the most appropriate and cost-effective surgical treatment for UF.

Management of Uterine Fibroids: A Focus on Uterine-sparing Interventional Techniques

Uterine fibroids occur in approximately 50% of women over the age of 40 years, and an estimated 50% of those are symptomatic. Menorrhagia is the most common symptom and the primary indication for treatment, although bulk symptoms often occur and can be treated. Pharmacotherapy is typically inadequate unless it can be expected to successfully bridge to menopause or allow for a less-invasive intervention. However, hormonal therapies have risks. Hysterectomy is still the most commonly performed procedure for symptomatic fibroids and has the lowest rate of reintervention (compared with myomectomy or uterine artery embolization [UAE]), but rates of more serious complications are higher and patient satisfaction and ability to return to normal activities may also be less favorable. Myomectomy is not necessarily less morbid than hysterectomy and may have a greater failure rate than UAE. Techniques and devices vary with little standardization, and operator experience is crucial to success. The largest studies of UAE show very low rates of serious complications and rapid recovery. UAE significantly improves symptoms related to uterine fibroids in 85%-90% of patients. Herein, this article will discuss the nature of fibroids and their diagnosis, pharmacotherapy, surgical treatment, and nonsurgical interventional treatment, including UAE and magnetic resonance-guided focused ultrasound.

Cost and Distribution of Hysterectomy and Uterine Artery Embolization in the United States: Regional/Rural/Urban Disparities

Hysterectomy, the driving force for symptomatic uterine fibroids since 1895, has decreased over the years, but it is still the number one choice for many women. Since 1995, uterine artery embolization (UAE) has been proven by many researchers to be an effective treatment for uterine fibroids while allowing women to keep their uteri. The preponderance of data collection and research has focused on care quality in terms of efficiency and effectiveness, with little on location and viability related to care utilization, accessibility and physical availability. The purpose of this study was to determine and compare the cost of UAE and classical abdominal hysterectomy with regard to race/ethnicity, region, and location. Data from National Hospital Discharge for 2004 through 2008 were accessed and analyzed for uterine artery embolization and hysterectomy. Frequency analyses were performed to determine distribution of variables by race/ethnicity, location, region, insurance coverage, cost and procedure. Based on frequency distributions of cost and length of stay, outliers were trimmed and categorized. Crosstabs were used to determine cost distributions by region, place/location, procedure, race, and primary payer. For abdominal hysterectomy, 9.8% of the sample were performed in rural locations accross the country. However, for UAE, only seven procedures were performed nationally in the same period. Therefore, all inferential analyses and associations for UAE were assumed for urban locations only. The pattern differed from region to region, regarding the volume of care (numbers of cases by location) and care cost. Comparing hysterectomy and UAE, the patterns indicate generally higher costs for UAE with a mean cost difference of $4223.52. Of the hysterectomies performed for fibroids on Black women in the rural setting, 92.08% were in the south. Overall, data analyzed in this examination indicated a significant disparity between rural and urban residence in both data collection and number of procedures conducted. Further research should determine the background to cost and care location differentials between races and between rural and urban settings. Further, factors driving racial differences in the proportions of hysterectomies in the rural south should be identified to eliminate disparities. Data are needed on the prevalence of uterine fibroids in rural settings.

The direct and indirect costs of uterine fibroid tumors: a systematic review of the literature between 2000 and 2013

This systematic literature review was conducted to summarize the direct and indirect costs per patient that are associated with uterine fibroid tumors in international studies. A search with predefined search terms was conducted in MEDLINE and EMBASE for studies that were published from January 2000 to November 2013. The review included primary studies that were in English and that reported either direct costs (drug costs, procedure costs, and medical service costs) or indirect costs (such as productivity loss) among patients with uterine fibroid tumors. A total of 26 studies that were identified and included in the data extraction included 19 studies in the United States, 2 studies in the Netherlands, 1 study each in Germany, China, Italy, and Canada, and 1 study reported data that were collected from 3 countries: Germany, France, and England. The studies differed substantially in perspectives that were adopted for analysis, research designs, data elements that were collected, setting, populations, and outcome measurements. Among 3 studies that reported total direct costs during the year after uterine fibroid tumor diagnosis, 2 studies reported an average of $9473 and $9319 per patient, respectively; 2 studies reported the excess costs over controls to be $6076 and $5427, respectively. The indirect costs per patient ranged from $2399-15,549, and the excess indirect cost per patient over control groups ranged from $323-4824 in the year after the diagnosis. The total costs, sum of direct and indirect costs, ranged from $11,717-25,023 per patient per year, after diagnosis or surgery among patients with uterine fibroid tumors. Compared with control subjects, the additional annual cost ranged from $2200-15,952 per patient. The results of this systematic literature review highlight the substantial direct and indirect costs that are associated with uterine fibroid tumors to health care payers and society. The large number and the variety of studies identified also emphasize the growing awareness of the significant economic impact of uterine fibroid tumors. Current gaps that were identified through this review warrant further investigation to elucidate fully the economic burden of uterine fibroid tumors, including, but not limited to, burden from the patient's perspective and the entirety of indirect costs.

Healthcare utilization and costs among women diagnosed with uterine fibroids: a longitudinal evaluation for 5 years pre- and post-diagnosis

OBJECTIVE

To evaluate the healthcare utilization, treatments, and costs incurred by women with uterine fibroids (UF), compared to those without UF, for 5 years before and 5 years after diagnosis.

RESEARCH DESIGN AND METHODS

This is a longitudinal, retrospective case-control study. A total of 84,954 women with a diagnosis of UF, along with matched controls of women without UF, were selected from the Truven Health MarketScan claims database (2000-2010). The date of diagnosis of the UF patient was assigned as the index date for both the UF patient and her matched control.

MAIN OUTCOME MEASURES

Healthcare resource utilization, treatments, and costs (in 2010 USD) were evaluated annually for the 5 year periods before and after the index date.

RESULTS

UF patients had more outpatient and emergency room visits than controls before diagnosis, and more inpatient, outpatient, and emergency room visits than controls after diagnosis. Annual total healthcare costs were significantly higher for patients than controls during the last 3 years pre-index and all 5 years post-index. Overall, the difference was $12,623 over 10 years, with a difference of $1435 in the 5 years pre-diagnosis and a difference of $11,188 in the 5 years post-diagnosis. The cost difference between UF patients and controls was highest in the first year post-diagnosis, reaching $6131, and the difference was even larger when comparing clinically symptomatic UF patients to controls. The use of medications and surgical procedures related to UF peaked in the year post-diagnosis, with 39% of patients receiving a surgical treatment within the year.

KEY LIMITATIONS

UF patients included in the study did not include undiagnosed and potentially asymptomatic UF patients; the impact of disease severity on the costs of UF patients was not evaluated.

CONCLUSIONS

Patients with UF incurred significantly higher healthcare utilization and costs than those without UF, both pre- and post-diagnosis.

Cost-effectiveness of magnetic resonance guided focused ultrasound for the treatment of uterine fibroids

OBJECTIVES

The aim of this study is to evaluate the cost-effectiveness of Magnetic Resonance Guided Focused Ultrasound (MRgFUS) compared with alternative treatments for uterine fibroids in the United States.

METHODS

We used techniques of decision analysis and data from secondary sources to develop and estimate an economic model of the management of uterine fibroids among premenopausal women. Patients in the model receive treatment with MRgFUS, uterine artery embolization (UAE), abdominal myomectomy, hysterectomy, or pharmacotherapy. The model predicts total costs (including subsequent procedures) and quality-adjusted life-years (QALYs) for each treatment strategy over a lifetime horizon, discounted at 3 percent, from a societal perspective. Data on treatment efficacy and safety were obtained from published and unpublished studies. Costs (2005 US$) were obtained from an analysis of a large administrative database and other secondary sources. Lost productivity costs were included in the base-case analysis, but excluded in a sensitivity analysis.

RESULTS

UAE was associated with the most QALYs (17.39), followed by MRgFUS (17.36), myomectomy (17.31), hysterectomy (17.18), and pharmacotherapy (16.70). Pharmacotherapy was the least costly strategy ($9,200 per patient), followed by hysterectomy ($19,800), MRgFUS ($27,300), UAE ($28,900), and myomectomy ($35,100). Incremental cost-effectiveness ratios (cost per QALY gained) were $21,800 for hysterectomy, $41,400 for MRgFUS, and $54,200 for UAE; myomectomy was more costly and less effective than both MRgFUS and UAE. Results were sensitive to MRgFUS recurrence rates, MRgFUS procedure costs, and assumptions about quality of life following hysterectomy.

CONCLUSIONS

Our findings suggest that MRgFUS is in the range of currently accepted criteria for cost-effectiveness, along with hysterectomy and UAE.

Midterm clinical and first reproductive results of a randomized controlled trial comparing uterine fibroid embolization and myomectomy

The purpose of this study was to compare the midterm results of a radiological and surgical approach to uterine fibroids. One hundred twenty-one women with reproductive plans who presented with an intramural fibroid(s) larger than 4 cm were randomly selected for either uterine artery embolization (UAE) or myomectomy. We compared the efficacy and safety of the two procedures and their impact on patient fertility. Fifty-eight embolizations and 63 myomectomies (42 laparoscopic, 21 open) were performed. One hundred eighteen patients have finished at least a 12-month follow-up; the mean follow-up in the entire study population was 24.9 months. Embolized patients underwent a significantly shorter procedure and required a shorter hospital stay and recovery period. They also presented with a lower CRP concentration on the second day after the procedure (p < 0.0001 for all parameters). There were no significant differences between the two groups in the rate of technical success, symptomatic effectiveness, postprocedural follicle stimulating hormone levels, number of reinterventions for fibroid recurrence or regrowth, or complication rates. Forty women after myomectomy and 26 after UAE have tried to conceive, and of these we registered 50 gestations in 45 women. There were more pregnancies (33) and labors (19) and fewer abortions (6) after surgery than after embolization (17 pregnancies, 5 labors, 9 abortions) (p < 0.05). Obstetrical and perinatal results were similar in both groups, possibly due to the low number of labors after UAE to date. We conclude that UAE is less invasive and as symptomatically effective and safe as myomectomy, but myomectomy appears to have superior reproductive outcomes in the first 2 years after treatment.

Payer Costs in Patients Undergoing Uterine Artery Embolization, Hysterectomy, or Myomectomy for Treatment of Uterine Fibroids

PURPOSE

To compare health resource use and medical costs in patients with uterine leiomyomas treated with hysterectomy, myomectomy, or uterine artery embolization (UAE).

MATERIALS AND METHODS

Patients who underwent hysterectomy, myomectomy, or UAE for leiomyomas were identified from a nationally representative private payer claims database based on their diagnosis and procedure codes. The study included patients with no prior hysterectomy, myomectomy, or UAE and no previous diagnosis of gynecologic cancer. Health resource use and medical costs were evaluated over a period of 12 months.

RESULTS

The study included 2,836 hysterectomy, 704 myomectomy, and 125 UAE patients. Average patient ages were 46 years for hysterectomy, 38 years for myomectomy, and 45 years for UAE (P < .001). Median UAE procedure costs were $5,968, compared with $7,299 for myomectomy (P = .031) and $7,707 for hysterectomy (P < .001). Median total 12-month payer costs were not significantly different among the three procedures ($10,519 for UAE vs $9,652 for myomectomy [P = .372] and $10,044 for hysterectomy [P = .813]). There were no differences in overall hospital admissions or emergency room visits after the procedures. Patients who underwent UAE had greater fibroid-related hospital and physician office use beyond 30 days after treatment (P < .001). During this period, 65.6% of patients treated with UAE had at least one imaging study, versus 37.1% of those treated with myomectomy (P < .001) and 14.1% of those treated with hysterectomy (P < .001).

CONCLUSIONS

Procedure costs were significantly lower for UAE versus myomectomy and hysterectomy, but there was no difference in total 12-month payer costs. Postprocedural imaging appears to be a factor in total UAE costs. Further research is needed to better understand the role of imaging studies after UAE.
